Description

Technical Field

[0001] The utility model relates to the technical field of disposable pulse irrigators, in particular to a wound cleaning device for general surgery. Background Technique

[0002] During surgeries in the field of general surgery, patients who need to have their wounds cleaned before further surgery are often encountered. Firstly, the purpose is to reduce infection, promote tissue repair. Routine irrigation, removal of foreign bodies and necrotic tissues are important steps to ensure wound healing.

[0003] A disposable pulse irrigator is a medical device for cleaning wounds. By rotating and squeezing the irrigation pipeline with a driving motor, it generates jet, fan-shaped and other spraying methods, thereby playing a role in cleaning wounds. It consists of a gun body, an irrigation nozzle and a connecting pipe, etc., and can be divided into different types according to different surgical needs. The use of this product can improve the convenience and safety of surgeries and reduce the risk of surgical infections.

[0004] When in use, a disposable pulse irrigator will cooperate with a waste liquid collection bag to collect the waste liquid generated during cleaning. The waste liquid collection bag is adhered to the patient's skin with tape to wrap the wound area, and its irrigation nozzle is inserted through an opening on one side of the waste liquid collection bag to perform the irrigation operation on the wound;

[0005] During this process, since the opening area of the side opening of the waste liquid collection bag is larger than the outer diameter of the irrigation nozzle, in order to prevent the irrigation waste from splashing out through the side opening, medical staff need to manually press and close the side opening of the waste liquid collection bag to make it fit against the outside of the gun body end. This operation causes inconvenience to the wound cleaning. Based on this, a wound cleaning device for general surgery is provided. Content of the Utility Model

[0026] The clamping assembly 2 includes an upper clamping block 202, a first connecting arm 203, a first pressing U-shaped block 204, a lower clamping block 205, a second connecting arm 206, a second pressing U-shaped block 207, and a compression spring piece 208;

[0027] The upper clamping block 202 and the lower clamping block 205 are symmetrically distributed up and down and sleeved on the outer side of the gun body 101. The upper clamping block 202 and the lower clamping block 205 are used to clamp and fix the side opening of the waste liquid collection bag;

[0028] The first connecting arm 203 and the second connecting arm 206 are respectively fixed at one end of the upper clamping block 202 and the lower clamping block 205. The first pressing U-shaped block 204 and the second pressing U-shaped block 207 are respectively fixed at the bottom of one end of the first connecting arm 203 and the top of one end of the second connecting arm 206. The first pressing U-shaped block 204 is sleeved on the outer side of the second connecting arm 206, and the second pressing U-shaped block 207 is sleeved on the outer side of the gun body 101. The first pressing U-shaped block 204 and the second pressing U-shaped block 207 are arranged in a staggered manner in the horizontal direction;

[0029] The compression spring piece 208 is distributed between the inner side of the first pressing U-shaped block 204 and the lower surface of the gun body 101 and between the inner side of the second pressing U-shaped block 207 and the upper surface of the gun body 101. The compression spring piece 208 is used to provide a thrust for the first pressing U-shaped block 204 and the second pressing U-shaped block 207;

[0030] The clamping assembly 2 further includes an anti-slip convex ring 201 and an anti-slip groove 209;

[0031] The anti-slip convex ring 201 is fixed on the outer side of the gun body 101 and near the front end of the gun body 101. A plurality of anti-slip convex rings 201 are arranged in the horizontal direction, and the plurality of anti-slip convex rings 201 are distributed on the inner sides of the upper clamping block 202 and the first connecting arm 203;

[0032] The anti-slip groove 209 is opened on the inner sides of the upper clamping block 202 and the first connecting arm 203 and corresponds to the position of the anti-slip convex ring 201 one by one. The upper clamping block 202 and the first connecting arm 203 can realize a corrugated clamping of the side opening of the waste liquid collection bag through the cooperation of the anti-slip groove 209 and the anti-slip convex ring 201.

[0033] In this embodiment, it should be noted that the inside of the gun body 101 is composed of a micro motor and a piston. The micro motor drives the piston to reciprocate, causing the internal volume of the piston chamber to change. When the volume increases, the flushing liquid is sucked in through the connecting pipe 102, and when the volume decreases, the flushing liquid is pressed out from the flushing nozzle 103, so as to achieve the purpose of flushing the wound. In addition, a wire (not shown in the figure) electrically connected to an external power supply is provided on the gun body 101. Since the above structures are all existing technical structures and do not involve the technical improvement of this solution, they will not be elaborated herein.

[0034] During use, a waste liquid collection bag is used to collect the waste liquid generated during cleaning. The waste liquid collection bag is adhered to the patient's skin with tape to wrap the wound. The flushing nozzle 103 is inserted through an opening on one side of the waste liquid collection bag to perform the flushing operation on the wound.

[0035] During this process, the first pressing U-shaped block 204 and the second pressing U-shaped block 207 can be manually pressed first, so that they squeeze the compression spring piece 208 to further contract. At this time, the upper clamping block 202 and the lower clamping block 205 move away from the gun body 101, so that the anti-slip convex ring 201 is exposed.

Then, the pressing on the first pressing U-shaped block 204 and the second pressing U-shaped block 207 is released. At this time, the upper clamping block 202 and the lower clamping block 205 are reset and approach each other under the action of the two compression spring pieces 208. Finally, the upper clamping block 202 and the lower clamping block 205 press the edge of the opening on the side of the waste liquid collection bag tightly to fix it outside the gun body 101.

[0036] In this way, when performing the wound cleaning operation, there is no need to manually press the opening on the side of the waste liquid collection bag, making the cleaning operation more convenient.
